To all whom it mayooncern:

Be it known that I, ROBERT MACKAY, a subject of the King of Great Britain, residing at .74: Shernhall street, Walthamstow, in the county of Essex, England, have invented a new and useful Kettle or WVater- Heater, of which the following is a specification.

The object of the present invention is to construct an improved kettle or Water heater which is adapted more particularly for use in restaurants and other places where it is advantageous to be able to draw boiling; water or to obtain a supply of steam from the same outlet for heating, forinstance,teapots. According to the present invention the .main body of the kettle has an upwardly tension of the body of the kettle where it is ward boiling water will be delivered through the spout, whereas when said part is in its normal or upright position steam will be delivered through the said spout. In some cases the said part may be moved backward to raise steam. The movement of this said part causes relative movement between the kettle and the valves and this mo ing part may be the body of the kettle in which case the valves are weighted so that they do not move with the kettle or the moving part may be in the form of a lever in Which ease the body of the kettle does not move.

Various methods of carrying the invention into effect are illustrated in the accompanying drawings which are somewhat dia grammatic. Figure 1 1s a side elevatlo-n partly in section and Fig. 2 1s a horlzontal SGCtlOIbOIl the line 22. of Fig. 1 showing a kettle heating medium is adapted to be turned on and off as the kettle is tilted backward or forward to deliver steam or boiling water.

Fig. 5 is a side elevation and Fig. 6 is a plan of part thereof showing a kettle in which the gas or other heating medium is adapted to be turned on and off by movinga lever backward or forward.

Fig. 7 is aside elevation partly in section and showing a section of a water valve and Fig. 8 is an elevation of part of a kettle showing a lever for operating a gas and a water valve simultaneously.

Fig. 9 is a plan of part of a kettle showing' a steam valve in section.

F in. 10 is a plan of part of a kettle show ing electrical heating means and a switch in section.

In all the figures a is the lower or main body of the kettle and a? is the reduced upper part thereof. The main body a of the kettle has an upwardly extending hot water delivery pipe. 6 which eXtends into the part (4 below the water level and is always open at its lower end. At its upper end the hot water pipe 5 enters another tube a, which acts as the pouring spout and steam. delivery pipe. This tube 0, which is preferably curved at its front or delivery end, enters at its rear end the upward extension (1 of the kettle, and it is provided with a steam valve which is opened or closed by tilting the kettle backward or forward or by the movement of a lever.

In the construction shown in Figs. 1 and Q? the tube 0, at its rear end, is formed with a valve seating c and a weighted valve 0 The cold water inlet tube (5 is mounted in bearings d, and has a branchcl which entcrs the body a. This branch 0Z is provided, at its rear end, with a valve seating (i and a hinged weighted closing valve 0Z The tube (l, at one end, enters a union 0Z which allows the tube 0! to rotate in its bearings al The union d is connected to the water supply pipe e, which is connected to a ball valve tank is which regulates the height of water 3 in the kettle. In the position shown in Fig. I '1, the valve d is open and water may enter 1 the kettle until it is shut olf by the ball valve. v In the same position steam is being delivered through the pipe 0, as the valve 0 is open. When the kettle is tilted forward the water inlet valve (Z and the steam valve 0 are both closed, and boiling water then passes up the tube Z) and is delivered through the spout. A is a gas burner to heat the vessel a.

In the construction shown in Figs. 3 and l, the parts Z), 0, c and 0 are like the parts shown in Figs. land 2 andoperate in like manner. The kettle a, m in this construction 1 is mounted on trunnions f, one of which :is'show-n and this may be a water inletitube connected to the ball valve tank by a union asshown in Figs. 1 and 2. This union, or the inner end of the water inlet tube, may be provided with a valve '1) which .is open when the kettle is horizontal or tiltedibaclnvard and which is closed when the kettle is tilted forward from the hori- 'zontal position, such a valve D is shown in section in Fig. 7. The perforated outer part 19 is fired rigidly to the-body part a [and moves therewith over the water inlet tube whichsis cut away .as shown. The bodyc aofthe kettle carries a cam g, the ends of which act against aspring plunger 19 to open the gas valve 9' when the kettle is tilted backward .or forward from the central horizontal position. In the-central hori- I delivered througha'thespout. If one of the trunnions is not a water inlet tube, the

upper part'a of the kettle is provided with a ifillingzorifi e'a nnd .screw stopper .05

In the construction shown in Figs. .5 and 6,}thefkettle is a'fixture' andthevalves are operated thy the :movement backward or forward 'fromxthecentral positionof the lever-h pivoted .totth kettle atxh T he: steamvalve c 'iszmounted upoirta shaft 0 on 'theendof which :is fixed the crarikc, which is connected 'bythe rod. 1L :with the lever h. In

the central "and backward positions of the lever h, :the valve :0 remains open. In the forward .position of'the lever hythe valve 0 will 'be c'l osed against its seating 0 The lever his shown with a square h toengage arwatercock D such as-that shown in Fig. 7 connected :to -a ball valve tank. In this construction the lever "h operates the outer part I) around the fixed water inlet tube f.

The parts D and f are shown dotted in Figs. 5 and 8. In the center position, and when the lever 72. is pushed backward, the water-cock D will remain open, but when the lever h is pulled forward, the water inlet cock will be closed. At its lower end the lever h carries a cam g, similar in shape to that shown in Figs. 3 and 4, and which acts upon the-spring plunger g of the gas valve as described with respect to that figure. If desired the lever 7t, pivoted at 71), may as shown in Fig. 8 carry a second cum i having a :projection 2' atone endonly and arting upon a spring plunger formingpart of a water inlet valve j Tlns cam i-will be arranged to leave the plunger in its outer position and the water inlet open when the lever h is central or pushed backward. The cam z'zwill, however, push-the spring plunger j inward and close the water inlet valve j when the lever h is pulled forward.

It will be understood that steam or electricity may be used instead of gas as the heatingmedium, and that what is described as :the gas valve 9 may be a steam valve or electric switch operated by the cam and turned off when the lever it is in its middle position and turned on when the lever la is in a forward or-backward position. Such a steam valve is is shown in Fig. -9 in which is a spring pressed plunger having a perforation at 70*. The valve is is bored through at 70 As shown in the drawing th valve is is closer but when the cam g is moved forward or backward it depresses the plunger s and the perforation L comes in alinement with the passage is and allows steam to'flow therethrough and to the steam pipes la -shown in Fig. 9.

Fig. 10 shows an electric switch operated by the cam g. The switch comprises a swing pressed plunger Z which enters the switch body 1. Through'this body and insulated therefrom are two contact blades Z The plunger Z has an insulation block Z at its lowerrend and when the plunger Z is depressedby theeam 9 moving forward or backward, it causes the blades ll to make contact with each other and allows current to pass to the electricheaters indicated diagrammatically at Z in Fig. 10, which heaters are located below the water in the kettle. When the level it is pulled forward, the steam and water valves being closed and the heating medium being in operation,-steam pressure will accumulate and deliver water through the pipe I) and spout. When the lever h is pushed backward steam only will be delivered.
